There is a really good web site that has pictures of a homebuilt smoker with this system. I have not taken pictures of mine.
If they work the way they are supposed to, you should be able to regulate the heat better throughout the entire smoker. One thing I had a problem with is the top of the smoker was always so much hotter than the bottom. I think maybe I didn't get my firebox low enough, so the passage between the firebox and cook chamber is too high. Hopefully the reflector will cure this problem and not smother my fire.
I didn't have internet back when I started this project some 10 years ago. So the only reference I had was a Brinkman at the Wally World, and I only looked at it once. I have gotten a lot of great information from the web and here.
